Structure of motor variability in marginally redundant multifinger force production tasks.
TL;DR: One subject showed different relations between VUN and VCOMP, suggesting that these relations did in fact reflect particular central strategies of solving the tasks, and the UCM method is applicable to force production tasks.

Understanding finger coordination through analysis of the structure of force variability.
TL;DR: The results lead to the suggestion that successful task performance is achieved, not by selecting a single optimal solution, but by discovering an appropriate control law that selectively stabilizes certain combinations of degrees of freedom relevant to the task while releasing from control other combinations.

A mode hypothesis for finger interaction during multi-finger force-production tasks

TL;DR: It is shown that a simple formal model based on modes with only one free parameter accounts for finger forces during a variety of multi-finger MVC tests, and its value depends only on the number of explicitly involved fingers.

Finger coordination during discrete and oscillatory force production tasks
TL;DR: The findings are interpreted as demonstrations of a limitation in the ability of the central nervous system to organize a twofinger synergy such that errors in the timing of individual finger force profiles are canceling each other’s effects on the total force.
